The lamp sounds like it may be out. That's usually the first step in fixing a RPTV like this.

Its a V24 chassis---it will blank or turn the picture tubes off for a number of reasons--all self protection. Someone would have to look---I presume when you say no picture you mean no light of any kind on the screen.

If no raster (no light of any kind on the screen) problem could be in Vertical or Horizontal sweep circuits which covers quite a few possible parts.

If the set had for example a blue screen only or is stuck on one input there is always to possible hard reset but that will not cure no raster.

I have a WS-55805. Was working great, then suddenly no picture, just audio. When I press the Menu button, I get the menu but I see three separate colors for each menu item. Could this be the lamp, or...


This TV does not have a single lamp but a set of CRT tubes.

If you get menu displayed on wrong clors or colors are not matching then it is either a bad CRT, a bad CRT high voltage power board, or sometimes a problem with convergence board and convergence ICs, however in this last case you usually get no picture and no sound .


You can get service manual from link below:

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

Screen goes black


If you are willing, remove the speaker grill and the rectangular board behind that and look very, very carefully underneath each of the three picture tubes for evidence of coolant drops on the printed circuit boards. These sets have been known to spill a few drops of coolant onto the boards and this causes intermittent problems such as yours. This is my first direction in your case. Let me know.

Mits ws-55805 No sound no Pictuer


FIRST CHECK CONNECTOR "DR" FOR PROPER CONNECTION, BETWEEN THE DEFL MINI PCB AND THE MAIN PCB. 2. CHECK C5A09 AND C5A50 BOTH 33 UFD 50 V OFF OF IC5A01 ON PCB-DEFL MINI. 3. CHECK FOR LEAKY IC5A03 PART # 270P704010 ON PCB-DEFL MINI 4. SUSPECT THE HIGH VOLTAGE BLOCK PART # 920P016010 IF STILL NO HELP PROBLEM CAN BE INTERMITTENT (TEMPERATURE RELATED) CAUSED BY IC7D04 PART # 275P245010 ON THE DOUBLER PCB THIS WOULD BE A THIN VERTICAL LINE IN CENTER, IF GUNS WERE ON.
